金字塔是一种三维几何形状,由多边形的所有角连接到中心顶点而形成。
金字塔有很多种类型,通常以其基底类型命名。下面我们来看看一些常见的金字塔类型。

四棱锥的体积 [金字塔的底部是正方形] = (1/3) * (b^2) * h
三棱锥的体积 [金字塔的底部是三角形] = (1/6) * a * b * h
五棱锥的体积 [金字塔的底部是五边形] = (5/6) * a * b * h
六棱锥的体积 [金字塔的底部是六边形] = a * b * h
以下是计算金字塔体积的代码:
// C# Program for volume of Pyramid.
using System;
class GFG
{
// Function to find the volume of
// triangular pyramid
public static float volumeTriangular(int a,
int b,
int h)
{
float vol = (float)(0.1666) * a * b * h;
return vol;
}
// Function to find the volume
// of square pyramid
public static float volumeSquare(int b,
int h)
{
float vol = (float)(0.33) * b * b * h;
return vol;
}
// Function to find the volume
// of pentagonal pyramid
public static float volumePentagonal(int a,
int b,
int h)
{
float vol = (float)(0.83) * a * b * h;
return vol;
}
// Function to find the volume
// of hexagonal pyramid
public static float volumeHexagonal(int a,
int b,
int h)
{
float vol = (float)a * b * h;
return vol;
}
// Driver Code
public static void Main()
{
int b = 4, h = 9, a = 4;
Console.WriteLine("Volume of triangular"+
" base pyramid is " +
volumeTriangular(a, b, h));
Console.WriteLine("Volume of square "+
"base pyramid is " +
volumeSquare(b, h));
Console.WriteLine("Volume of pentagonal"+
" base pyramid is " +
volumePentagonal(a, b, h));
Console.WriteLine("Volume of Hexagonal"+
" base pyramid is " +
volumeHexagonal(a, b, h));
}
}

输出:
Volume of triangular base pyramid is(三角形底面金字塔的体积为) 23.9904
Volume of square base pyramid is(正方形底面金字塔的体积为) 47.52
Volume of pentagonal base pyramid is(五角形底面金字塔的体积为) 119.52
Volume of Hexagonal base pyramid is(六角形底面金字塔的体积为) 144
